Ditch the Aggregate devices for a start ( yes it’s expensive running a lot of inputs or outputs on a proper system, and you don’t take advantage of all the interfaces built into gear). Uninstall Blackhole and spend the money on Rogue Amoeba stuff. Buy audio interfaces with good drivers (e.g. RME, Lynx, Metric Halo or even MOTU AVB stuff and stay away from Antelope - they have problems), install, plugin and away you go.
